High-strength water pipe for pipeline engineering and method for preparing high-strength water pipe

Abstract

The invention provides a high-strength water pipe for pipeline engineering and a method for preparing the high-strength water pipe, and relates to the technical field of plastic pipes. The high-strength water pipe comprises, by weight, 40-50 parts of polyethylene terephthalate, 20-30 parts of polyurethane, 10-16 parts of vermiculite powder, 0.8-1.2 parts of octadecyl di-(2-hydroxy ethyl) methyl ammonium chloride, 0.3-0.5 part of sodium dodecyl benzene sulfonate, 15-20 parts of glass fibers, 5-10 parts of 1, 2-polybutadiene, 4-9 parts of nanometer silicon nitride, 4-9 parts of carbon black, 4-9parts of graphite powder, 2-4 parts of titanate coupling agents, 2-4 parts of flame retardants, 2-4 parts of plasticizers and 2-4 parts of heat stabilizers. The high-strength water pipe and the method have the advantages that the high-strength water pipe is stable in property, excellent in weather resistance, heat resistance and acid and alkali resistance, high in strength, good in pressure resistance, long in service life and easy to produce, and raw materials for the high-strength water pipe can come from extensive sources.

Description

technical field [0001] The invention belongs to the technical field of plastic pipes, and in particular relates to a high-strength water pipe for pipeline engineering and a preparation method thereof. Background technique [0002] With the intensification of urbanization, the construction of pipeline engineering is also in full swing. As an important part of pipeline engineering, water pipes are responsible for transporting water bodies. Existing water pipes generally use PVC materials, but the flame retardant performance of PVC water pipes is not high enough, and a large amount of black smoke and toxic gases will be emitted when burning, such as carbon monoxide, benzene, naphthalene and other aromatic compounds, which seriously endanger people's health, and even Threat to people's lives. In addition, PVC water pipes on the market have poor pressure resistance and are prone to problems such as water leakage, water seepage, and rupture, which greatly reduces the service life...

Problems solved by technology

Existing water pipes generally use PVC materials, but the flame retardant performance of PVC water pipes is not high enough, and a large amount of black smoke and toxic gases will be emitted when burning, such as carbon monoxide, benzene, naphthalene and other aromatic compounds, which seriously endanger people's health, and even threaten people's lives

In addition, the PVC water pipes on the market have poor pressure resistance and are prone to problems such as water leakage, water seepage, and rupture, which greatly reduce the service life of PVC pipes and limit their application range.
